Exercises 4 - 10 Flashcards
Primary effect of elevator
Pitch
Primary effect of aileron
Roll
Primary effect of rudder
Yaw
Secondary effect of rudder
Roll
Secondary effect of roll
Yaw
Yaw causes roll because of (2)
Outer wing moves faster than inner wing, generates more lift.
Dihedral Aircraft has outer wing presented to airflow at greater angle of attack, generating more lift
Secondary effect of elevator
Changing airspeed
Why are ailerons’ effectivity not affected by power changes
They are outside the slipstream
3 ways to increase lift
Increase airspeed.
Increase angle of attack.
Increase camber.
Slipstream effect most pronounced under conditions of
High power and low airspeed
High power and low airspeed makes slipstream effect more pronounced because (2)
Corkscrew is tighter and angle of attack is greater
Normal (clockwise) slipstream causes what control effect
Left yaw
Reducing power causes a
Pitch down tendency
Increasing power causes a
Pitch up tendency
Effect of raising flap
Nose pitches down and airspeed increases
Effect of extending flap
Nose pitches up and speed reduces
Mixture should be fully rich below
3000’
Whilst taxying, always
Pull elevator towards you
Level flight check
Power 2200RPM, Attitude, Trim
FREDA
Fuel, Radio, Engine, Direction, Altimeter
Scanning check
Lookout, Attitude, Instruments
If neither straight nor level:
Level wings, set correct pitch attitude, check balance
Straight and Level at 2350 RPM, gives you an attitude at
95kts
Straight and level at 1900 RPM, gives you an attitude at
70kts
If climbing/too fast while straight and level
Reduce power, adjust attitude, re-trim
If descending/too fast
Leave power, higher attitude, re-trim
Straight and level with flap
Power 1900 RPM
20 degree flap
Power 2200 RPM
